Z hldhEa-Liii Specification of Letters Patent. Pggg iggd J @119; 29 1gpApplication filed. June 15, 1914.. Serial No. 845,411

To aZZ whom it may concern:

Be it known that we, (1) Dr. loos E. Hin- NEH and (2) Fnnonmon WVLINAKER, (1) a citizen of-the United States and (2) a subject of theKing of England, residing at Dubois, in the county of Clear-field andState of Pennsylvania, have invented certain new and useful improvementsin Boiler- Flue-Gleaner Systems, of which the following is aspecification.

This invention relates to boiler flue cleaner systems, of the typeemploying a fluid-distributing pipe provided with discharge nozzles, sodisposed with. relation to the longitudinal axial center of saidpipe,'and

to a bank of boiler tubes as to discharge steam or other cleaning fluidin oblique streams through the spaces between the boiler tubes.

The present invention is designed as an improvement upon the type offlue cleaners disclosed in United States Letters Patent No. 1,041,01' 9granted to De Los E. Hibner under date of Oct. 15, 1912, and in UnitedStates Letters Patent No. 1,O&1,1 l1, granted to James Moore, Oct. 15,1912.

In Letters Patent No. 1,04c1,07 9 above 'referred to, a plurality offluid-distributing pipes is employed, each having a plurality ofdischarge nozzles interposed and arranged to discharge fluid atan'obliiple line with respect to the axis ofthe distributing pipe andfine. The other patent above re ferred to, No. 1,044,141 embodies thefee tures just described, in combination with means for rotating thedistributing pipes to vary the angular positions of the dischargenozzles with relation to the boiler fines, and thereby change thedirection of oblique travel of: the stream of cleanin fluid, to sheet acleaning of the entire sr'lrr'ace oft-he tubes.

The primary object of this improvementis to accomplish the results aimedat by both of the patented inventions above-idem tified, by greatlysimplified means, and to materially reduce the cost of installatiozr ofboiler flue-cleaning apparatus operating on the principle hereinbei'foreoutlined.

Another object, and an important one of this improvement, is to provideintersecting cones of blast without the streams of fluid forming saidcones crossing each other when issuing from the directing nozzles.

will lie in different planes radiating from the longitudinal axis of thefluid-distributing pipe, the nozzles being angularly-displaced aroundthe pipe, preferably providing a sp1ral arrangement, the degreepfangularity however, being variable as conditions may -leqllll.

The invention will be fully described hereinafter in connection with theaccompanying drawings which form a part 01" this specification, and itsdistinguishing features over the prior art will be set forth and definedin the appended claims.

In the drawings: Figure 1 is a. view in elevation, with the boilersetting broken away showing a flue cleanersystemembodying the'invention,it being understood that inlpractice, the branch pipes and feed pipe areoutside the boiler setting as shown in .lfig 2- F g- .2 is a horizontalsectional view of a'boilersettingshowing a top plan of the 'cleanersystem installed in'position with relation to the tubes of aboiler ofthe wellkn own B and W. type. Fig. 3 is a transverse vertical sectionalvieW of a boiler and its setting as shown in Fig. '1, and partly brokenaway to show the arrangemei'it and disposition of the nozzles of thedistributing pipes with respect to the passage-ways be tween adjacentrows of tubes. Fig. 4., is a detail plan view partly broken away, of oneof the fluid-distributing pipes. Fig. 5 is a section on the line V-V ofFig. 4. Fig. 6 is a detail plan view similartojfiig. e of a modifiedconstruction of liquid-distributing pipe. Fig. 7 is a section on theline Vll VH of Fig. 6, and, Fig. 8 is a detail view partly in sectionshowing one end of the-rotatable fluid-distributing pipe located in thesoot chamber of the boiler setting.

thusadapt- When the improvement. is applied to a boiler of the typeshown, the construction and arrangement of the nozzles of the distributing pipes enable us to arrange the d1s tributing pipes at spacedpoints directly 16 extend upward from the'feed line at desired intervalsand each is provided with a shut-off valve 17 preferably located at apoint close to the feed line. Elbow plpes 18 connect the upper ends ofthe branch pipes- 16 with the distributing pipes 19 arranged above thetubes 20 of the boiler. These distributing pipes are extended throughone side wall of the boiler setting and may be j ournaled at their innerends in the opposite side wall, but we prefer to support the pipesintermediate their inner-ends and the installation Wall by means ofbracket clamps as 17 which are clamped on the water tubes of the boilerbeing provided with openings for the distributing pipes so as toconstitute journals for the latter. A branch pipe 21 connected with thefeed line 10 at a suitable point extends down to the soot chamber of theboiler setting, and is connected with a transversely-disposeddistributing pipe 22, rotatable on its longitudinal axis and preferablyjournaled at the inner end in the opposite wall. The pipe 22 has aplurality of openings or nozzles disposed intermediately throughout thelength of the pipe to discharge the cleaning fluid which may be directedto all parts of the soot chamber to create a strong blast of steam whichwill carry out through the stack the soot which has been dislodged fromthe tubes, together with the accumulation that has lodged in said sootorcombustion chamber. Thenozzles 25 of the pipes 19 are so disposed thatthe cleaning agent is projected between the lines of the different rowsof tubes as best shown in Fig. 3, so that steam issuing from the nozzleswill be projected through the space 26 in such a manner that as thedistributing pipe is rotated, the arc traversed increases so that theprojected steam strikes the tines more or less as the bottom Hues of thebattery are reached, the steam being projected in the space cleaning thefiues on opposite sides and its later contact with the fines directserving to dislodge all soot which may-have dropped thereon from thefines above. In order to keep the soot cleaned from the sides of theboiler setting, each distributing pipe is provided adjacent the endswith an opening as 29, projecting downwardly at direct "right angles tothe axis of the pipe, and cleaning the inner side of the boiler setting,as well as the tines which arelocated adjacent to such sides of theboiler setting. l

The numerals 30 and 32 designate the usual headers, and 31 and 33, thebafileplates-of a B. and N. boiler, and the disposition of the pipes 19is such that the steam from the nozzles 25 is directed in oblique:streams between all of the tubes or flues of the battery.

' As shown in Figs. 4 and 5, the nozzles 25 are disposed at differentradial angles to. each other, preferably at angles of between twenty andthirty degrees, but the precise degree of angular'ity may be varied.

In Figs. 6 and 7 we have shown a modification in which the nozzles 25 ofthe distributing pipe 19 are disposed at points diametricallyopposite'each other. This arrangement is within the scope of theinvention, as well as all such further modifications as will insure theissuing of the steam in streams of varying obliquity, so that the numberof distributing pipes to clean the entire battery of fines is reduced tothe minimum, only four of such pipes being necessary in. the embodimentshown in Figs. 3 and 4.

It will thus be seen that any pairof the in such manner as to producetwo cones of blast when the pipe 19 is revolved but that the streams offluid producing these cones do not interfere. so that there is notcaused an appreciable change of direction of these streams such as wouldoccur did the streams intersect.
